Updated How we research

hygger double sponge filter size S with 2 spare sponges, a small-tank air filter that comes with ready replacements.
AQUANEAT Aquarium Bio Sponge Filter Breeding Fry Betta Shrimp (Large up to 60Gal)
AQUANEAT large bio sponge filter for tanks up to 60Gal, an air-driven filter that is safe for fry, bettas and shrimp.
Sponge filters run on an air pump that pulls water through a porous sponge, which traps debris and grows a large colony of beneficial bacteria. They are prized in planted and shrimp tanks for their gentle, shrimp-safe flow and for how simply they can be rinsed and reused. There are no impellers to catch tiny livestock, which makes them a go-to for breeding tanks and nano scapes. Sponge filters suit shrimp keepers, fry-rearing tanks, and anyone who wants cheap, reliable biological filtration with almost no risk to small creatures. The trade-offs are visible equipment inside the tank and a bit of bubble noise from the air pump. Many aquascapers hide them behind hardscape or plants, or pair them with another filter for polish. If your priority is safe, stable biological filtration for delicate livestock, a sponge filter is hard to beat.
